Specification of Letters Patent.

Application filed February 16, 1911.

Serial No. 609,024.

To all whom it may concern:

Be it known that I, JAMES S. Pou'rnn, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

The object of this invention is the provision of an improved and inexpensive stopper for bottles which renders it extremely diflicult, if not impossible, to introduce liquid into a bottle but permits the contents of the bottle to be freely poured out.

In the accompanying drawings: Figure 1 is a fragmentary vertical section of a bottle equipped with my improved stopper, the parts being shown in a position which they occupy when the bottle is upright. Fig. 2 is a similar view showing the position of the parts when the bottle is tipped over into its pouring position. Figs. 3 and 4 are horizontal sections in the correspondingly numbered lines in Fig. 1. Fig. 5 is a detached perspective view of the valve, guard and weight bar connecting the valve and guard, of my improved bottle stopper.

Similar letters of reference indicate corresponding parts throughout the several views.

1 represents the body of the bottle and 2 the neck thereof which is provided with an enlarged lower part 3 forming an outwardly facing valve seat 4 at the inner end of said enlargement and an inwardly facing beveled annular shoulder 5 at the outer end of said enlargement. WVithin the bore of the contracted or narrow outer part 6 of the neck of the bottle is secured a plug 7 of any suitable material which is provided in its central part with a plurality of longitudinal passages or perforations 8. This plug may be secured in place by any suitable means but preferably by means of one or more V-shaped spring dogs or catches 9 each of which has its inner end arranged in a circumferential groove 10 on the periphery of the plug while its outer end engages with an annular groove 11 in the bore of the contracted outer part of the neck of the bottle.

12 represents an outwardly opening valve arranged within the enlarged part of the neck and movable toward and from the valve seat for opening and closing the bottle.

13 represents a guard which preferably has the form of a cup which is dished inwardly and which has its edge provided with a plurality of notches or recesses 14.

15 represents a weight bar which connects the valve and guard and which is deflected laterally so that when the bottle is tipped the bar will always depend relatively to the valve and guard.

The valve, guard and weight bar may be made of any suitable material and held in place relatively to each other by any suitable means but the same are preferably constructed in one piece of glass, porcelain or similar material.

At the outer end of the outer side of the weight bar the same is provided with an outwardly facing beveled face 16 which is adapted to engage with the beveled shoulder 5 of the enlargement.

In assembling the parts of the bottle the valve, guard and weight bar are first passed through the narrow part of the neck into the enlarged part thereof and then the plug containing the dogs in a compressed condition in its peripheral groove is pushed into the narrow part of the neck until the dogs reach the annular groove in this part of the neck at which time the dogs expand into the neck groove and securely lock the plug against lengthwise movement in the neck, thereby preventing the parts of the stopper from being withdrawn. The parts of the stopper are thus inserted in the bottle after the latter has been filled with the liquid which is to be packed. Wile the bottle is in an upright posit-ion the valve rests on the seat and is held there by its weight together with the weight of the guard and the bar connecting the guard and valve, as shown in Fig. 1. Upon tipping the bottle until its axis reaches a horizontal position the valve will be still held against its seat by reason of the weight bar hanging downwardly from the valve and guard and the engagement of its beveled face 16 with the beveled shoulder 5 of the neck, whereby an inward pressure is produced on the valve and the same is effectually held against its seat so as to prevent the escape of liquid from the bottle and likewise prevent illicit introduction of liquid into the bottle in this position of the same. Upon tipping the bottle so that its axis is below horizontal the valve, guard and bar move outwardly in the enlarged part of the neck inasmuch as the weight of these parts at this time overcome the cooperating inclines 5 and 16 on the Patented May 21, 1912.

with the valve by pushing a wire inwardly through the passages in the plug will be frustrated inasmuch as such wires are intercepted by the dished surface of the guard and prevented from reaching the valve.

I claim as invention:

The combination of a bottle having its neck provided with an enlargement forming an outwardly facing valve seat at the inner end of said enlargement, a perforated plug secured in the neck beyond the outer end of said enlargement, an outwardly opening :valve arranged in said enlargement andadapted to engage said valve seat, a guard having a free concave outer side provided at its edge with notches and adapted to engage with the underside of said plug, and a weight bar connecting said guard and valve and deflected to one side of the axes of said valve and guard and provided on the outer side of its outer end with a beveled face which is adapted to engage with a beveled shoulder at the outer end of the enlarged part of the neck.

VVitness my hand this 15th day of February, 1911.
